Motörhead were forced to cancel Saturday's (June 22nd) concert at Austria's See-Rock Festival and have cancelled tonight's show (June 25th) in Milan as well because Lemmy has suffered a hematoma and is unable to go onstage, according to a Facebook post by the Italian promoter.

A hematoma is a mass of usually clotted blood caused by a broken blood vessel that forms in a tissue, organ or body space. They can occur anywhere in the body, and the prognosis varies widely. Specific information on the cause, location and severity of Lemmy's hematoma has not been released.

Lemmy recently went through an operation for serious heart issues and now has a defibrillator embedded into his chest. If it detects cardiac irregular heartbeat, it automatically delivers a jolt of electricity to correct it.

We wish the legendary Lemmy a speedy recovery, and hope that he's back on stage in the near future.

Motörhead's next full-length album will be called 'Aftershock'. The record is reportedly expected to see a September release, but stay tuned for full details on the album as news breaks.
